The
Evolution of the GSM Radio Subsystem
The commercial drive for
low-cost, compact, and long battery life handsets, along with the
requirements for multiband (for internetwork roaming), multislot EDGE
(for higher data rates) functionality, has motivated significant
advances in the GSM radio subsystem, including its antenna and IC
constituents. In addition to technical performance margins against
regulatory standards for high production yields and base
station/mobile device link quality, key drivers in this RF technology
evolution have mainly been: low cost, increasing levels of
integration towards reduced component count and PCB area utilization,
and low power consumption.
Bluetooth
and WiFi integration: solving co-existence
challenges
Recent advances in wireless
networking technology provide the means to revolutionise the way
information is delivered. The promise of un-tethered and seamless
access to information anywhere, anytime, is leading to a dramatic
increase in applications and use scenarios.
